I gave up trying to fix that with Apple. I have a ticket opened for that, number 374243158. Today Apple contacted me to inform that iTunes do not support HD movies converted by third party applications, like Handbrake.
They assume the limitation or how iTunes is designed.
Good luck for you and happy new year.

Unfortuntely like many others I had no luck in finding a simple fix for the choppy 1080p videos issue that occurr in itunes for pc. I will how ever tell you that I just purchased a new imac and transferred all my videos (including the 1080p videos) to my new itunes on my mac. I have played several of the videos that were choppy on my pc on my new imac and they play perfectly. Defiently a issue with itunes for pc, and really Apple should look into this as there are a lot of pc users running itunes and if they don't fix it some may find other programs to store and play their media. This would be a huge loss for Apple, especially as our future of digital media is growing phemonially and movies seem to be moving from 720p to 1080p. Well hope this help some of the pc users with this issue.

I don't think this is just a Windows issue. I have the same issue on my late 2009 Mac Mini (2.26 GHz Intel Core 2 Duo, 4GB RAM). I used Handbrake to convert a load of 1080p HD demos complete with 5.1 AC3 soundtrack, using the AppleTV 3 preset. I imported these into iTunes 11 on my Mac Mini (which is connected to my HD TV, and AV receiver) and hit play. The 5.1 surround sound track played back fine, with no issues - but the videos played back choppy with dropped frames. At first I thought it was due to my Mac Mini not having enough horse-power to play the 1080p video without choking (seeing as it's a few years old now). However, I then tried playing the same files in VLC player on the same machine - and they play back flawlessly and silky smooth. - It's definitely something to do with the way iTunes handles the files, and is far more resource heavy.
Some people have suggested restarting the machine helps - but it has made no difference in my experience. I tried the same video files on my newer MacBook Pro Late 2011 (2.2 GHz Intel Core i7, 4GB RAM), inside iTunes 11 - and they play fine with no issues. - So it seems to suggest a faster machine helps. No doubt the windows version of iTunes is even worse than the Mac version, so this problem may be even more apparent.

Guys... If any of you are still following this thread, I think I finally found a solution... When having this issue sporadicially I got sick of it because I KNOW my computer can run these videos... so.. I once again for the ten bazillionth time googled it... and I finally found a site that explains the issue. The issue affects both Windows and Mac, howver it seems to be worse on Windows. As for a faster computer, yes that WILL help, but that's not how to fix it...
Basically what his site says is... the problem is your idevices syncing wirelessly. While he says only Apple knows for sure WHAT it's doing, iTunes is apparently constantly looking for your devices... and that's what's causing the iTunes to lag!!! After following his instructions... I just watched the second ten minutes of a 1080HD show that was very choppy the frist ten minutes before turned off all my wireless syncing. So, this may be a workaround until **** freezes over and Apple actually acknowledges and fixes this issue.
I wil however note that some of you MIGHT not have the minitum ITUNES requirements to run 1090HD video, as it's apparenlty 2.4ghz. I've got 2.23 though, and I'm running just fine again now... so good luck to the rest of you, hopefully you'll still be good to go like me!

I did not try this new cancel wifi workaround because I love the wifi sync. this has only been a minor issue for me because we watch all of our itunes content on the apple tv.
You can use VLC to play all videos, and you can simply right click on the video in question, select Find in windows explorer, then right click and choose Play in VLC.
However, I do understand that itunes is great as a media device, and you may not want to do this.
I will then offer the best solution I can...without trying to sound like an apple snob.
Get a Mac.
There is no reason anymore not too. Prices are not as great as they used to be.
So maybe you cant afford that 27" imac, I cant either. But you can get a nice mac mini and I promise you it will run your 1080 videos just fine in itunes.
Im using an old 2007 imac with a 256mb video card, its a 2.8 ghz core2duo running 3 gb ram mac osx Mavericks. Plays full 1080p videos in itunes just fine.
So go buy a used one, pawn shops are full of imacs. Ebay is full of imacs.
Imacs really are well built, and last long. they are more upgradable than people think. You can add more ram, you can increase the hard drive capacity by adding an SSD hd (you may not be comfortable doing it, but macsales.com is a company that will).
I have a brand new HP quad core, i even put a video card in the computer, I still get the itunes lag.
Here is the kicker..if you really NEED windows, you can install windows on any mac using parallels or bootcamp.
No reason not to go to a mac anymore, which is why they have gone from 1% market share to almost 10% now. Without loosing their great customer satisfaction rankings.
Dont take my word for any of this. google it.
And remember, your computer will run snappier when you dont constantly have to run an antivirus program. Ive never run one since 2005, the year I made the change.
and in case you want to know why I have a PC....I have 14 TB of videos on hard drives that I need to access. Using USB is too slow, so I took out all the optical drives of the HP and have 4 hard drives inside. then networked it as a server. all for 500.

Um okay no VLC will not play iTunes videos (at least not purchased ones, as they are protected) unless there is some way to get VLC to ask iTunes for authorization that I don't know about.
